  • Patent number: 8045018
    Abstract: An imaging processing unit signal-processes main picture data outputted from an imaging device. A zoom processing unit subjects the signal-processed main picture data to picture resize processing. A display picture management unit subjects the signal-processed main picture data to resize processing by the zoom processing unit to generate display picture data, aside from the main picture data recorded onto a recording medium at the time of photographing, and temporarily stores the display picture data in a memory area set inside or outside the integrated circuit. A display picture processing unit subjects the main picture data and the display picture data to display processing.

    Abstract: In a stereoscopic imaging device including a plurality of imaging optical systems, a wide-image in which a principal subject is shifted from the center is taken, and also, a tele-image in which the principal subject is enlarged is taken at the same time. A size of a wide-side frame W, that is, a size of an angle of view of a trimming wide-image is decided based on a size of a tele-side frame T, that is, a zoom magnification of a tele-side imaging optical system, a position of the wide-side frame W displayed in the decided size is arbitrarily moved depending on an instruction from an operation unit, an area delimited by the wide-side frame W moved to any position is clipped from a default wide-image, and thereby, the trimming wide-image is obtained. Thereby, the tele-image which is a telephoto image in which a desired subject is zoomed, and the trimming wide-image which is a wide-angle image in which the subject can exist at a position other than the center of the image are simultaneously obtained.

  • Patent number: 7817195
    Abstract: An apparatus and method of automatic conversion to a digital zoom mode allow a digital zoom to be executed by automatically converting from a high-resolution mode that does not support a digital zoom to a highest resolution mode supporting the digital zoom when a digital zoom key is pushed. The apparatus includes a key pad having a digital zoom key, a video processing unit for processing video data from the camera unit to determine a resolution and execute a digital zoom function, and a control unit for controlling the video processing unit to convert a resolution mode that does not support the digital zoom function to a highest resolution mode among resolution modes supporting the digital zoom function and execute the digital zoom function when the digital zoom key is pressed in the resolution mode that does not support the digital zoom function.

  • Patent number: 7812875
    Abstract: The signal processing circuit of the present invention comprises a drive unit and a processing unit for picture signal. The drive unit supplies each of the shift pulses separately to the electronic shutter shift register and the readout shift register. The processing unit for picture signal designates a control start position of a digital picture signal outputted from an A/D converter and performs interpolation processing thereon along the horizontal direction and the vertical direction. The drive unit adjusts cycles of each of the shift pulses for controlling a vertical-line readout rate of the solid-state imaging device, and then intermittently reads out the analog picture signal from the solid-state imaging device. The processing unit for picture signal performs vertical-line interpolation processing in accordance with the vertical-line readout rate for extending a part of picture area of the digital picture signal.

    Abstract: A camera body 3 includes a cross control key 27 and a body microcomputer 10. The body microcomputer 10 can acquire lens information related to an interchangeable lens unit 2 from the interchangeable lens unit 2. The body microcomputer 10 decides whether or not the interchangeable lens unit 2 is compatible with electric zoom on the basis of lens information. The body microcomputer 10 also activates zoom operation at the cross control key 27 on the basis of this decision result.
